xMPRoym/IENTIN NECK-Yeahs;

-f-m-w The semoule refer-reale m there Letter Panne and talking-pgn of the stime.

To c llwhom, -it may concern l Be it known that I, CLARK' S. SANFORD, of Lena, in -the county of Stephenson, andState of Illinois, lmveinvented a new and useful Improvement in Neck- Yokes; and I do hereby'declare that the following is 'a full and exact description of the same, reference being had to the accompanying drawings, and to the let? ltersot reference` marked thereon. h This invention relates to that class of neckfokes in which rack-bars are usedin connection witha pinion, `for the purpose of permitting the lateral 'adjustment ofthe end-rings, without moving the pole; and consists in tnetgnemicombnation"and' arrangement of the .various parts.

' The details of construction and manner of operation willl be fully' described hereinafter. 1

In the draw-ings- Eigurel isa -plan view of my invention inverted;

Figure 2i a similar view of one ofthe racks; and Figures 3 and d, sectional views, through lines :c :c

and y y. fig. .1. .l

To enable'othersskilled in the art to make and use my invenfticm will `A`now proceed to describe its con` stmction'j'and operation. y

A represents the neck-yoke proper, which is-construct'edofanysnitable form and size. y

B B represent rack-bars, which are constructed with 4teeth lgdlanges b1, arms b2, and slides b. These bars -areloated in suitable sockets in the lowerside oftheueckyok,e,"amlhave room for lateral movement.

G reprbseiitsafpiniom whichv is' also provided 'with a flange, c. Instead of passing the centre-bolt through l the pinion, as -is nsuzvththe latter is pivoted in any suit able manner, and the bolts pass through the yoke upon each side, as shown.; j

d d representplates located at each end of the-yoke, the edgesjof which project over the groove a, and' form ways upon which move the slides bJ of the rack-bars,

the-latter being provided with fianges,as shown, above Vand below the edges of the plates, so that displacement i is rendered impossible.

The outer ends of the arms bare either provided with small rings to receive the large rings for the breastchains, or with a staple to receivethe pole-straps.

E represents a covering-plate, by means of which. the internal parts are protected.

The operation of my yoke is similar to otliersvof this, class. The end-rings may-be adjusted laterally when,

desired, "by the simple movement ofthe animal.

The advantages of the special construction shown, are as follows 2^ First, by providing 'the rack-hals'aud the pinion with flanges, their strength is so much increased that much smaller sizes cau be used, and hence, Athey may be employed with buggiesland light carriages, where.

heretofore. the excessive size andweight of this class oi' yokes has rendered them wholly unfit for such use. Second, by providing 'the rackbars with arms and slides, as shown, the'bearing-surfaceis much reduced,

and consequ ently,1tlie friction is. also. hird, by the combination and arrangement of the various-parts, a light, yoke is 'produced 'which at the same time possesses great"strength.

Having thus fully described rnyuvention, That I' claim las new, anddesire to 'secure by Letters Patent, is-

The neck-yoke described, consisting otlthe yoke A,

' flanged bars B, pinion C, and ways d, the whole being combined and arranged as and for the purpose described. .1
